Here are top adventure-friendly hotels near Unawatuna (good for snorkeling/diving, surfing lessons, whale-watching trips, kayaking and easy access to Jungle Beach, Rumassala and Galle Fort). Short notes on what makes each one adventure-ready and a source.

• Cocobay Unawatuna — beachfront hotel with on-site water‑sports (surf lessons, kayaking), PADI/diving excursions arranged and whale‑watching day trips from Mirissa offered through the hotel. Great choice if you want easy access to snorkeling, surf classes and organized boat trips. (cocobayunawatuna.com)

• Thaproban Pavilion (and Pavilion Waves) — beachfront resort with watersports, snorkeling and diving options nearby, bike/surf/yoga facilities and a tour desk for whale‑watching and national‑park excursions; positioned at the far end of Unawatuna bay for quick access to Jungle Beach and Rumassala walking/hiking.

Quick planning tips

• Whale watching: seasonality matters (best months typically mid‑November to April from Mirissa area); many Unawatuna hotels arrange transfers/tours. (Hotel pages above list whale‑watching as an excursion option.) (booksurfcamps.com)
• Diving/snorkeling visibility and surf conditions are seasonal — check directly with the hotel dive/activities desk before booking specific dives or surf lessons. (oyster.com)

If you’d like I can:

• Narrow this to a specific budget (backpacker, midrange, luxury).
• Check live availability, nightly rates and exact activity offerings for dates you plan to travel (I’ll need the travel dates to look up current prices).
